Be' it known that 1, LoUIs Scriwirzniz, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and `useful Oiling System, of which the tollowin is a specification.

'he object of my invention is to produce a base casing structure for internal combustion engines of such character that all of the bearings will be supplied with an adequate quantity of lubricating oil. l

The accompanying drawings illustrate my invention.

Figure l is a vertical section o n line .1 1 of Fig. 3;- Fig. 2 a plan 1n partial horizontal section; Fig. 3 an end elevation; Fig. 4 a sectionon line 4 4 of Fig. 1 of the upper casing member; Fig. a section on line 5-5 of Fig. 1; and Fig. 6 a sect-ion of the upper casing member on line 6- 6 of Fig. l.

In the drawings, 10 and 11 indicate, -respectively, upper and lower hollow casing members which mate upon a plane which extends through the bearings for the crank shaft 12, shown -in dotted lines in Fig. 1. The crank shaft bearings are formed. 1n

bushings 13, 14 and 15, each of which is preferably a continuous or circular bushing, and in order. to receive these bushings,

the upper casing member is provided with semi-cylindrical bushing pockets 13', 14' and 15', respectively, which are formed in portions preferably integral with the casing member. Detachably secured to the members 13, 14' and 15', respectively, are cap members 13", 14", and 15" of ordinary form, Formed through the end Walls of the member 10 are aliiied bushing pockets 16 and 17- in which are mounted bushings 16 and 17', respectively. Formed in' integral portions of member 10 in alinement with-the bushing pockets 16 and 17 are in termediate bushing pockets 18 in each of which is. mounted a bushing 18j. which are in alinementwith the bushings 16' and 17' and formed to receive and support a'cam shaft 19 indicated in dottedlines in Fig. 1. Formed within casing 10 above the bushing pockets 16. 17 and 18, is a closed oil chamher .21 which extends the entire length of the ,casing and is provided withaplurality of outlets 22 each of which leads to a bushing pocket 16, 17 or 18. Opposite each outlet 22 the corresponding bushing 16', l7fend l8r Specification offLetters Patent.

is providedwith a circumferential groove 23 an at its. top, each of these bushings is provided with. an oil passage 24 which leads from the bottom of the groove 23 to the bore .of the bushing. Leadin through the bot'.-

tom of each bushing'poc :et 18' is a passage 25. Leadin through the lower side of the bushing poc et 16 is an oil passage 26 which delivers into a basin 27 which is formed above the bushn pocket 13 and communi- Cates therewith t rough an oil passage 28. The bushing 13 is provided with a circumferential exterior groove 29 from which an oil passage 31 leads to the interior of the bushing. The bushing 13 is also provided along its bottom with a longitudinal groove 32 which leads from the lower part of the groove 29 to the end of ca y 13". The middie bushing pocket 18 lies above the bush; ing pocllret 14 and delivers oil through its passage 25 to an oil basin 33 which is formed in the upper surface of the bushing pocket through a passage 34. The bushin 14 is provided with a circumferentia g'roove 35V which registers with passage 34 and is provided with a passage 36 which leads from groove 35 tothe interior ofthe bushing. Thebushing cap ,14 is provided witha passage 37 which permits surplus oil to flow downwardly into the casing member 11. Bushing 17' is also provided with a circumferential external groove 38 from which a passage 39 leads to the top `of the bore of the bushing. A passage 41 formed through the bottonrof the bushing pocket 17registers at its upper end with groove 38 and at its lower end delivers into an oil pocket 42 which is formed labove the upper part of the bushing pocket 15. Bushing 15 is provided with' a circumferential external groove 43 which registers with a passage 44 leading from pocket 42 and also is provided with a passage 45 which leads from the groove 43 into the .interior of the bushing. A small passage 46 formed through a cap 15" permits the surplus oil to How into.the casing 11.

10oI Y Casing 11 is formed so as to produce a y mainor general oil reservoir 47 from which an oil outlet 48- delivers to a pipe 49 which is the suction pipe of an oil pump 51 which delivers through pipe .52 to oil chamber 21. Extending across the'interior of the bottom otmember 11. opposite each crank of" the is n comparatively narrow oil into eneb of which may flip e` carried by s. pinnen 5? on il crank shell.. rooghs e onnecierl in pairs by en inernieclioie 5Fl :ind the emi Weils 539 of Lne ol' the wells 59 and die pump el olf such character es lo cleliver oil lio chainber 2l in suoli queniiies es tol keep such chember full and the oil under pressure therein. Consequently the oil vvill be (le liverefl at 'e Considerable velocity irom chamber 51 through the various openings 22 enel from thence to the circumferential ,grooves of the bushings '16', i7 18. From these circumferential grooves o' suflicient quent-ity of oil for the bearings of the cam shaft will How into che ninterior of the bushings While the remainder of the oil will How erounel lirough the circumferenliel grooves enel be delivered through rho proper pas sages so the oil poelres 27, 33 and l2 and :from ehe intermedieee bushing pockets 18 'lo che 'l-rongghs 57.
